RFMW (San Jose, CA) has announced design and sales support for two “Small Cell” power amplifiers from TriQuint (Hillsboro, OR). The TQP2451 and TQP2453 support 1,900 and 1,800 MHz transmitter designs respectively. With average power output of 2.5 W, both devices include 3 gain stages, the final stage being a Doherty design for high peak power performance up to 20 W. The TQP2451 covers 1,930 - 1,995 MHz with power added efficiency of 38% and <-50 ACLR. The TQP2453 offers 35% PAE over 1,805 - 1,885 MHz. Both the TQP2451 and TQP2453 utilize 18 and 5 V Vcc. Both devices are offered in a 20 x 20 mm package for 3G/4G wireless infrastructure, linearized transmitters, MIMO, and heterogeneous networks applicable to small cells.

Specifications for each include:

TQP2451:

  • Frequency Min: 1.93 GHz.
